ACTION FOR PIPEHORGANS.

PEGIFICATION formngpart of Letters Patent No. 522,902, dated July 10, 1894.

Application filed January 18, 1894. Serial No. 497,279. (No model.)

To aZZ whom it may concern: Be it known that we, WILLIAM KING, residing at Elmira, Ghemung county, State of New York, and EDWARD J. KING, residing at Philadelphia, Philadelphia county, State of Pennsylvania, both citizens of the United States, have invented certain new and useful Improvements in Actions for Pipe-Organs; and we hereby declare the following to be a full, clear, and exact description of the same, refence being had to the accompanying drawings, wherein- 1 Figure'h is a cross section of so much of a pipe organ as is necessary to illustrate our invention, together with one arrangement of organ .action embodying our said invention, and Fig. 2, is a similar View showing a modification in the arrangement of lever, pallet and combining pull down wires.

Like symbols refer to like parts wherever they occur.

It is well known to those skilled in organ construction, that the wind pressure in the wind-chest and upon the pallets which admit the wind to the larger pipes of large and medium sized organs,v is too great to be easily overcome by the pressure of the fingers on the keys, consequent-ly the manipulation of such organs is laborious and tiresome; and it is also well understood that the required pressure on a key of an organ to actuate the pallet in the wind-chest, when under pressure, is the least when the pull down wire is connected with the pallet at a point nearest to the act-uated end, and that the first impact of the finger on the key overcomes the pressure of the wind on the pallet when the key has been depressed one-halt the dip allowed for the same, but the whole dip of the key or range of movement of the pallet actuating mechanismv required to fully open or pull down the pallet is increased in proportion as the connection of the pull down wire with the pallet recedes from pivot and approaches the actuated end of the pallet.

The object of the present invention is, therefore, to obtain such a construction of pipe organ action as will overcome the wind pressure on the pallet by a slight pressure of the linger on the key, and which will open the pallet fully with a limited range of movement in the pallet actuating mechanism.

To this end the main feature of our invention, embraces the combination with a pallet of a plurality of pull down wires connected therewith at dierent distances from the actuated end of the pallet, and means tor actuating the pull down wires successively.

A second feature, embraces the combination with a pallet and a plurality of pull dowii wires connected therewith, of a pivoted lever for actuating the pull down wires, said wires being` connected with the lever at different distances from the fulcrum.

There are other minor features of invention, all as will hereinafter more fully appear.

We will now proceed to describe our invention more fully, so that others skilledin the art to which it appertains may apply the same.

In the drawings l indicates the outer frame of the wind-chest, 2 the pallet box, 3 the pallet held in position by the pivot It and spring 5, and 6 the channel through which the wind passes to the pipes 7 placed over it, all of which may be as shown or of any other well known or desirable form.

Connected with the pallet at different distances from the pivot end are two pull down Wires 8 and 9 (see Fig. l), one of which is preferably attached thereto at the nearest accessible point to the actuated end of the pallet, and the other in rear thereof or nearer to the pivote, and said pull down wires pass down and are connected with a lever l0 having its fulcrum or pivot on a butt ll which may be secured by a screw l2 to a bar 13 or otherwise supported, as desired. The lower ends of pull down wires 8 and 9 are threaded, pass through suitable slots at different distances from the pivot or fulcrum of lever 10, and are provided with leather nuts 18 and 19 or other suitable adjustable connections.

I n the construction shown in Fig. l,-which is for some reasons the preferred construction, the pull down Wire 8 is connected to the pallet 3 at the nearest possible point to the actuated end, and passes through the pull board 20, also through the lever l0 at a distance of one inch and a halfli) from the ful- 1o about one quarter (il) of an inch below the under side of the lever, while the lever l is actuated by a tracker let provided with leather nuts for purposes of adjustment, a back :tall l and a sticker 1G, which connect it with the I5 key so that the lever l0 acts first as a lever of the second order and then as a lever of the third order, but all this detail may be varied by persons skilled in the art, as shall be determined by the installment, and without dezo parting,` from the scope or spirit ol` our invention. For instance, as indicated in Fig. 2, the lever may be a right angle l0, or other lever of the first order, and the connection of the pull down wires may, if desired, be reversed, all as indicated at S 9 of said Fin" O n' 7 and furthermore, though the lever l0 is herein shown as located outside ot the pallet box 2 because we deem that position best, it being' more accessible for purposes of adjustment,

3c yet it is apparent that said lever can be located within the pallet box it desired.

The action being` constructedsubstantially as hereinbefore specified will operate as follows: On the Vfirst impact ot' the finger on key 17 depressing it about one-half the dip allowed for the same, or to the dotted line (see Fig. l) this halt' movement given te the key is transmitted through the sticker 1G, backlall l5, tracker 14 (or equivalent mechanism) 4o to the lever 10 (or 10nd) and pull down wires 8 (or S) and D (or 9) connected with the pallet 3, and in case of the preferred construction (Fig. l) the pallet S is actuated first about one-half its proper movement and from a point where the pressure of the wind on the pallet is reduced to a minimum. At the same instant the lever l0 having,l been depressed so as to strike the leather nut at 19 ou the lower end of the pull down wire t), the pallet isturther actuated, and there being little resistance, other than the spring 5, which is easily collapsed, the pallet is opened the full width desired to allow a sufficient amount of wind to fiow from the pallet box, and this with the exertion of little power and with a limited range of motion in the actuating; devices.

Having thus described the nature, construction, and operation of our invention, what we claim, and desire to secure by Letters Patent, 1s

l. ln an organ acticn,the combination with a pallet, of a plurality et pull down wires, and means for actuating the pull down wires successively; substantially as and for the purposes specified.

2. In an organ action, the combination with a pallet, ot a pluralityof pull down wires and a lever for actuating' the pull down wires, said wires arranged to engage the lever at different distances from its Fulcrum; substautially as and for the purposes specified.

3. lu an organ action, the combination with a pallet, and a pivoted lever, cl' a plurality ot pull down wires, said wires connected with the pallet at different distances from the actuated end thereof and arranged to successively engage the lever at different distances from its fulcrum; substantially as and tor the purposes specified.

In testimony whereof we affix our signatures, in presence of two witnesses, this lth day of January, lSfll.
